COLUMBUS — Authorities at Ohio State University say a man with a knife tried to abduct two women in separate incidents near OSU Medical Center.

Both women ran away on Wednesday and were unharmed. The Columbus Dispatch reported one was approached at a bus stop by a man who held a knife with a 3-inch blade to her side and told her she was coming with him and he was going to rape her. The other woman was grabbed near her car.

The university sent a text message alert to more than 30,000 recipients and warned people to be aware of their surroundings when walking around campus.

University police Deputy Chief Richard Morman said officers questioned a man Wednesday night. There was no immediate word of any charges filed.
